ELEVATOR-DOOR-OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 476,773, dated June 14,1892.

Application filed December 12, 1891- Serial Na. 414,856. (No model.)

T0 all whom it nuty concern:

Be it known that I, GEORGE NV. ARCHER, of Rochester, in the county ofMonroe and State of New York, have in vented certain new and usefulIinprovernents in Elevator-Door- Operating Devices; and l do hereby7declare the following to be a full, clear, and eXact description of thesame, reference being had to the accompanying drawings, forming a partof this specification, and to the figures of reference marked thereon.

My present invention has for its objects to provide a device forOperating the doors of elevator shafts or Wells, whereby the move- Inentof the car or cage will serve to open the door when it approaches afioor, maintain it open while the car is standing there, and close itagain positively when the car inoves in either direction; and to theseand other ends the invention consists in certain novelties inconstruction and combinations of parts, all as will be hereinafterdescribed, and the novel features pointed out particnlarly in the claims at the end of this specification.

In the drawings, Figure 1 is a view looking from the shaft toward thedoor, showing the Operating devices in the well and on the car. Fig. 2is a horizontal sectional view on 'the line w x of Fig. 1; Fig. 3, aside view of the devices on the car and well; Fig. 4, a sectional viewon the line y y of Fig. 1.

Similar reference-numerals in the several figures denote similar parts.

The car or cage 1 of the elevator may be of the ordinary or anypreferred construction, upon the front side of which is arranged astandard 2, said standard having at top and bottom bearings for a shaft3, to which is connected a rack at by arms 5 and G,the latter beingcontinued rearward and downward, forming an Operating handle or leverfor turning the rack and shaft to the positions shown in full and dottedlines, Fig. 2. A spring 7, connected to the lever G and Operating on thestandard, tends to move the rack into the position'shown in dottedlines, Fig. 2, out of engagement with a gear-wheel, farther ondescribed.

The door 8, one being arranged at each floor, may be of any desircdconstruction, though I prefer to make it, as shown, of strips 9, securedto a backing 10, of canvas or similar flexible material, and to provideguides 11,in which it runs, extending upward and forward, as shown, saiddoor being counterweighted or supported on spring sash-balances, so thatit will require little power to run it.

Arranged at the side of the door-opening and within the well is a plate12, having a lug 13 at one side, and upon a bolt or pin 20, extendingthrough this plate, is pivoted a gear 111, having a crank-pin 18 thereonconnected by a connecting-rod or ptrnan 15 with the door 8. In thepresent instance this connection is formed by a lever 1G, pivoted at 30in the well, connected at one end to a link 31, pivoted to thelazy-tongs 17, which is in turn fastened to the lower end of the doorand at the other to the pitinan 15, the arrangement being such that whenthe Crank-pin on the gear is in lowest position, as in dotted lines,Fig. 1, the door Will be open, and when in highest position it will beclosed.

The rack 4, located on the car, is preferably beveled at the ends, asshown in Fig. 3, and the space between the lug 13 on the plate 12 andthe edge of lthe gear is such that when the rack is turned so as toengage the gear the lu g 13 will hold it in engagement against thetension of the spring 7 until it has moved out of engagement, when thespring will move the rack to the position shown in dotted lines, Fig. 2.Normally the rack on the car is in the position shown in dotted lines,Fig. 2, the door is closed, the pitman 15 being in line with the centerof the gear and the wrist-pin above thev center, so that it isimpossible to open the door eX- cept from withinthe Well, and the carcan be raised and lowered without Operating any of the doors in thewell. VVhen the operator in the car wishes to stop at any floor, justbefore he reaches it he moves the handle 6 so that the rack will be inposition to engage the gear and holds it there until the beveled endStrikes the lug 13, which latter will hold it in engagement with thegear, and the continued movement of the car Will rotate the gear ahalfturn, which will be accomplished When the car is level with thefloor, when the car may be stopped in the ordinary manner. The lug 2 vwawa 13 holds the rack in engagement and prevents the closing of thedoor until the car moves away, and then, no matter' in which directionit moves, the gear will be rotated a half-turn 5 and the door closed andlocked as before.

Instead of having the spring 7 hold the rack out of engagement, it couldas well be made to hold it in position to engage the gear, in whichevent all the doors would be opened and closed by the car unless it weredesirable to pass them. l/Vith this arrangement there is no possibilityof the doors being left open accidentally or of the doors being closedwhen the car is at the floor.

The device shown herein is simple, easily operated, and, I find inpractice, admirably adapted for the purpose.

I claim as my invention- 1. The combination, With an elevator-car andthe movable rack thereon, of a door leading into the elevator-Well, agear connected therewith, With which the rack engages and adapted by itsrotation to operate said door, and a stationary projection in the wellco-operating With the rack and retaining it in engagement with the gearWhile the car is in proximity to the door, substantially as described.

2. The combination, with an elevator-car and the rack pivoted thereon,of a door leading into the well, a gear connected thereto, with whichthe rack engages and adapted by its rotation to operate said door, and astationary lug in the Well co-opcrating with the rack and retaining itin engagement with the gear while the car is in proximity to the door,substantially as described.

8. The combination, with the door 'leading into the elevator-\vell,agear connected thereto and adapted byits rotation to operate said door,of an e1evator-car,a movable rack thereon, a spring for moving the rackout of engagement with the gear, and a stationary projection in the Wellco-operating with the rack and retaining it in enga-gement with the gearwhile the car is in proximity to the door,substantially as described.

4. The combination, with an elevator-car having the movable rackthereon, of a door leading into the well, the plate secured in the well,having the lug at one side, the gear connected to the door and Operatingby its rotation to open and close it, and the pivot-pin securing thegear to the plate, substantially as described.

5. In a door-Operating device for elevatorwells, the combination, withthe door and operating device therefor located in the well,ol` a car anda device on the car co-operating with the one in the Well for aetuatingthe door, capable of being moved out of co-operative position, and astationary projection or retaining device engaging the device on the carand maintaining the two devices in connection when once engaged untilthe door has been opened and closed, substantially as described.
